ALFRED CARSON, OF NEWV YORK, N. Y.

FIREPLACE.

Specification of Letters Patent No. 28,347, dated May 22, 1860.

To all whom it may concern:

Be it known that I, ALFRED CARSON, of the city, county, and State of New York, have invented a new and Improved Fireplace or Grate for Heating Apartments; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure 1, is a face or front view of my invention. Fig. 2 a horizontal section of the same taken in the line w, m, Fig. 1. Fig. 3 a vertical central section of the same taken in the line y, y, Fig. 1.

Similar letters of reference indicate corresponding parts in the several figures.

The object of this invention is to obviate the difficulty hitherto attending open grates or fire-places for heating apartments, towit: the escape of a large amount of heat up the chimney or flue the result being due to the encompassing of the back and sides of the fire-place or grate by the masonry of the chimney and the consequent small area of heat-radiating surface exposed, together with the very direct communication of the fire with the chimney or flue.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents the lower part of a chimney or flue and B, the mantel.

G, is a fire place of cast-metal, the lower part of which is of semi-cylindrical form and the upper part considerably contracted in depth so as to form a narrow passage a, into the flue A, the curved part b, of the fire place which contracts it at the upper part serves as a deflecting plate to throw the heat outward into the apartment as will be fully understood by referring to Fig. 3. The fire place is cast with a flanch c, at its front part which flanch laps over the edge of the mantel forming a finish to the same, as shown clearly in Fig. 1. At the back part of the lower portion of the fire chamber there is a narrow chamber E, the form of which is shown in Figs. 2 and 3. Directly over the chamber E, there is a damper cl, which, when open, forms a direct communication between the fire chamber and the flue as shown in Fig. 3. At the upper part of the passage 0;, there is a damper c, which is also shown in Fig. 3. F, is the ash-pit which is directly below the fire place G, and extends some distance out in front of it be yond the mantel. G, is a semi-cylindrical fender the ends of which are provided with hooks f, which fit in correpsonding recesses g, in the sides of the fire place as shown clearly in Fig. 3. This fender may have its upper edge inclined as shown clearly in Figs. 1 and 3, and it projects out in front of the fire place but not quite so far as the ash pit F.

H is a hearth-plate which is fitted around the fender G, and covers the front part of the ash-pit. This hearth-plate is provided with a horizontal plate h, to admit of a space or passage 2', through which and a passage j, air may be admitted into the ash pit, see Fig. 3, the passage j, communicating with a pipe or passage which leads outside the apartment and supplies the ash-pit with fresh or pure air.

I, is an inclined grate which is fitted in the fire chamber and extends down to the front and bottom part of the fender G. The grate I, is of circular form and rests on ledges or supports 72, and may be turned around to rid the fire place of ashes, the front part of the grate being provided with a pin which is accessible for the purpose of turning the grate by removing the hearth piece H, see Fig. 3. The lower part of the chamber E, at each side communicates with the apartment by pipes Z, as shown by the dotted lines in Fig. 2. The back of the fire chamber is perforated as shown at m, said perforations being just above the ate I.

From the above description it w1ll be seen that a very large grate I, is obtained, and consequently a large fire surface will be exposed and a large amount of heat radiated, the inclination of the grate together with its exposed position, one-half of it being in front of the fire place, insuring such result. The cold air also being drawn from the apartment at the sides of the chimney or flue, and passing through the chamber E, and ejected over the fire through the perforations m, as shown by arrows 1, serves to equalize the temperature of the apartment, while the pure and fresh air from without with which the fire is supplied as indicated by the red arrows 2, keeps the apartment supplied with pure warm air, the vitiated air being allowed to escape by means of proper eduction openings in the apartment. In kindling the damper d, is opened and When the fire is underway the damper 65, is closed and damper e, opened.

During summer or when a fire is not required the fender G, is covered by a semicircular plate J, and a mirror K, or any suitable fire board having a proper ornamentation may be fitted in the front of the fire place, see blue lines in Fig. 3. In converting the fire place into a summer arrangement, it Will be seen that the grate does not require to be removed nor any parts Whatever belonging to the fire place.

The Whole device is simple, economical and it is believed will obviate the objections hitherto attending the open fire-places or grates fitted directly in chimneys.

heating passage E, substantially as and for the purpose set forth. 7
